Predicting the Strength of Acid / Base. Can we predict the relative basicity of two
bases ? The stronger the acid, the weaker will be its conjugate base. (The larger
Remember that acidity and basicity are the based on the same chemical ... In the
following simple example the base, B, removes a proton from the acid, H-A: ...
